FILTER.

eas es.

To all whom it may concern Be it known that I, OSCAR M. LAMSENS, a citizen of the United States of America, residin at Detroit, in the county of Wayne and fitate of Michigan, have invented certain new and useful Improvements in Filters, of which the following is a specifica tion, reference being had therein to the accompanying drawings. V

In the process of filtering beer it is necessary not only that provision be made for handling a large quantity in a small space of time but also for readily cleaning and inspecting the filtering apparatus as the latter becomes quickly coated with albumen and other coagulated material which is difiicultapparatus and which is arranged for either single or double filtration.

The invention consists in the matters hereinafter set forth and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view, partially in side elevation and partially in section, of one form of apparatus that embodies features of the invention; Fig. 2 is a view in section taken on or about line IIII of Fig. 1; Fig. 3 is a view in side elevation, partially broken away and in section, showing the apparatus open for inspection; Fig. 4 is a view in section taken on or about line IVIV of Fig. 2; and Fig. 5 is a view in longitudinal section, enlarged, of a single filtering element.

As herein shown in preferred form a base 1 affords support for a pair of oppositely disposed standards 2, of suitable design and material to combine strength with lightness, that are pivotally secured to the base as on pins 3 and are adapted to be swung together and secured by bolts 4 near their upper ends. Stops 6 aid in supporting the standards in upright position while corresponding brack-v ets 7 hold the standards when turned into horizontal position as indicated in Fig. 3. A hollow trunnion 8 is journaled in one of the bearings 6 and supports on its inner end the crowned outer plate 9 and shell 10 of one section of a filter drum. The crowned plate and shell are secured together by bolts 11 passing through their margins and also serv- Specification of Letters Patent.

ing, in the disposition of parts shown in F lgs. 1, 2 and 3, to secure an apertured head 12 between them. The latter has a plurality of cylindrical filter members 13 secured on its nner face in substantially parallel relation to the axis of rotation of the drum. These each consist of a cylinder 14 of filter stone or like porous and permeable material that is clamped between a cap 15 and the head 12 by a rod 16 that fits an aperture in the head 12 and is in screwthrcaded engagement with a suitable outer nut 17 and inner nut 18. Preferably, a spring washer 37 is used on the bolt to prevent leakage from expansion. All the apertures of the head 12 are occupied by the filter clamping rod 16. Gaskets 19 are employed to prevent leakage around the ends of the filter stone and an outlet from the bore of the stone through the head 12 is provided through a suitable duct indicated at 20 in the bolt 16. A companion shell 22 and crowned plate 23,whose margins are secured as by bolts 24 over a head 25, are carried by a hollow trunnion 26 in a bearing 27 of the other one of the standards. Filter members 13 are secured to the head 25 in a similar manner to those on the head 12. The mating marginal flanges 28 of the two shells 10 and 22 may be secured together by suitablydisposed bolts 29. Suit able arranged fittings 30 on the plates 9 and 23 afford means for connection of a by-pass 31 that is preferably formed of flexible hose. An annular gear 32 is secured on one of the heads in mesh with a pinion 33 that is driven by a shaft 34 and pulley 35 that afford one means of rotating the shell although, obviously, other mechanism may be employed. Suitable stuffing boxes 36 on the outer ends of the trunnions 8 and 26 are used for connecting the latter with supply and outlet pipes. The space in the drum around the filter stones is about half filled with broken glass 39 or like abrading and noncorrosive materials.

In Fig. 1 a disposition of parts is shown wherein one of the heads as 12 is clamped between the flanges 28 of the two shells, the bypass 31 being omitted and the nipples 3O suitably closed or plugged.

In operation beer that is forced through the intake spindle 8 fills the entire drum and works its way through the stones into the hollow heads formed by the crowned plate, from whence it flows through the outlet trunnion 26, the by-pass 31 affording free communication between the heads. After the filter has been-in use, and the albumen and coagulents of the beer have coated the exterior surfaces of the stones, the filter is revolved by its drive mechanism so that the stones are scoured by the broken glass or like material in the drum. At'the same time filtered and sterilized water is forced through the filter in reverse direction, entering the bores of the stones and passing outwardly therefrom so as to readily remove any matter clinging to their outer surfaces. If it is desired to filter the beer twice, the arrangement shown in Fig. 4 is used, the liquid passing through the stones from the exterior to the interior.

When it is desired to clean the filter'more thoroughly and inspect it, it can be readily opened by disconnecting the shells and stand ards and swinging them down into horizontal position.

Obviously, changes in the details of construction may be made without departing from the spirit of my invention and I do 'not care to limit myself to any particular form or arrangement of parts.

What I claim is 1. A filter comprising a cylindrical casing journaled to turn on its axis and provided with heads having a plurality of openings theret-hrough, cylindrical filtering members each secured to a head. over an opening, means forming bearings for the shell at each end thereof and each having an inlet in communication with the several openings of the adjacent head, means in which the bearings are jou'rnaled, and means for rotating the shell therein;

2, A filter comprisin a pair of substantially cylindrical shell sections adapted to be secured together at their ends, a crowned plate detachably secured at the outer end of each shell, a hollow trunnionsecured to each plate, tiltable supporting means in which each trunnion is journaled, a head for each shell adapted tobe secured to either end thereof and provided with a plurality of cylindrical filter m embers, an outer plate for the outer end of each shell provided with a hollow trunnion forming a passage into the shell, tiltable supports in which the plate trunnions' are each journaled, and means for rotating the shell sections.

3. A filter comprising a shell, heads each adapted'to be secured to an end of the shell 7 and provided with inlet openings, a cylindrical filter member secured to each head over each opening, hollow trunnions each secured to the shell as a bearing therefor, and means for turning the shell in the supports.
